"A Passing Through" lyrics

There's nothing I can do
Nothing left to say
The birds have flown away
I step out on the sand
Release you from my hand
I know that you can't stay

Oh, you see
You left your mark on me
But it's true
I think I always knew
You were a passing through

I've walked too many roads
Seen enough to know
That life is letting go
Let love be the surprise
That trips you where it lies
Then runs into the night

Oh, you see
You left your mark on me
But it's true
I think I always knew
We were a passing through

Oh, and it doesn't get easier just cos you've done it all before
It doesn't get easier closing an open door
It doesn't get easier but that's what I'm waiting for
